It does seem to be the case that some people think having a Leica or Rolleiflex of Hasselblad will make them a better photographer. But the way it actually works: a reliable, high quality camera does what you want it to, so, if you make good photos, you're the one who did it and, if you make bad photos, you're the one who did it. It's not that you can credit the equipment - it's that you can't blame it.
Also, regarding quality and grain and abnormalities and defects: most photos are boring and all that stuff can make the mundane more interesting. People already see the world free of grain and (unless they have the wrong glasses) tack sharp. Show them something different.
